MANILA - (UPDATED) Horacio Castillo III, a law student at the University of Santo Tomas, succumbed to "extreme pain and suffering" in a suspected fraternity hazing that left his remains bloated and covered with bruises and burns, his father claimed Monday.

The 22-year-old student told his parents that he had been accepted to the Aegis Jvris fraternity after completing tasks like cleaning hallways and running errands for members. On Saturday, he attended the organization's welcoming rites at the UST campus, his father Horacio Castillo Jr. told ABS-CBN News.

The freshman law student never made it home.

A resident found Castillo's body dumped in a street in Balut, Tondo on the wee hours of Sunday. He was rushed to the Chinese General Hospital, but was already lifeless when he reached the hospital.

His family found him there after receiving a tip from an anonymous text message, his father said.
